Anything like Hinano's or The Shack in the Southbay?
How about Richmond's in El Segundo? Or Tavern on Main? (Although their burger isn't as good.)
Manhattan Beach has a Hennessey's outpost, which has ok burgers.

Big Mike's has a location I've tried on Main Street in El Segundo and another further south. Great Philly cheesesteaks, and I also really like their lightly battered onion rings. They do burger combos too, and I'll bet they're good, but I only remember one smallish flatscreen in El Segundo that was tuned at lunch to some espn.news type channel, without anybody paying much attention. Don't know what the atmosphere would be later on in an evening with a popular game on. I've had my share of burgers at the Shack on Wilshire -- some hot and messy and an excellent value, others seemingly served from a warming tray with an untoasted bun and less satisfactory. Big Mike's beats their pants for value, friendliness, and fresh deliciousness of the food.
wilafur, i was going to mention naja's. and as for naja's i'm pretty positve it has the most beers on top of any bar in the sisouth bay and la, and their variety of taps is much better than the yard house, which really isn't that interesting once you realize that most of the beers there are commercial ones.
little secret is that eurcoles in MB makes one of the best burgers in the south bay, especially their messy teriaki burger. they get their meat from butcher next door at manhattan market, and thats probably what makes it. its also got that divey atmosphere working too. might be tough getting a seat in there this weekend, however, with surf fest going on.
also you might want to try the kobe sliders in the bar at the new brix 1601 in hermosa. really tasty, but not a very shack-like atmosphere.
